Mozart: Maestro of Tonality is meant for a music lover, whether novice or aficionado. It is a study of his masterful tonality – “the core of music”—by discussing compositionally dynamic movements of harmony, agile key modulations, and artful character vocalizations. It illustrates Mozart’s deft melding of human and orchestra voices in key dramatic opera moments by presenting commentary on specific score excerpts. A short description of the book is: “Attuning aurally to Mozart’s scores.” A music lover, concertgoer, or opera fan may review a particular book section before and after attending a performance, or while listening to a recording, looking to anticipate and then rethink, or “rehear,” a particular transcendent aural moment. All will find a lively and detailed account of Mozart’s innate tonal gifts and his learned compositional prowess. In the case of his operas, this entails a tailoring of sound-to-singer portraits giving voice to the myriad aspects of human nature.
